Now I have comprehensive information to provide a detailed, well-structured answer. Let me compile it.
Section 375 IPC (Amended) — Definition of Rape & Evidence Collection in Rape Victims
Part I: Section 375 IPC — Amended Definition of Rape
Background
The original Section 375 IPC (1860) defined rape narrowly as penile-vaginal penetration only, with 6 circumstances (against will, without consent, with fraudulent consent, etc.). After the December 2012 Delhi gang rape (Nirbhaya case), the Criminal Law (Amendment) Act, 2013 (in force from 3 February 2013) comprehensively amended Section 375 based on the Justice J.S. Verma Committee recommendations.
Amended Section 375 IPC — Full Text
"A man is said to commit rape if he—"
(a) Penetrates his penis, to any extent, into the vagina, mouth, urethra, or anus of a woman, or makes her do so with him or any other person; or
(b) Inserts, to any extent, any object or a part of the body (not being the penis) into the vagina, urethra, or anus of a woman, or makes her do so with him or any other person; or
(c) Manipulates any part of the body of a woman so as to cause penetration into the vagina, urethra, anus, or any part of the body of such woman or makes her do so with him or any other person; or
(d) Applies his mouth to the vagina, anus, or urethra of a woman, or makes her do so with him or any other person —
under the circumstances falling under any of the following seven descriptions:
| # | Circumstance |
|---|
| 1 | Against her will |
| 2 | Without her consent |
| 3 | With consent obtained by putting her or any person in fear of death or hurt |
| 4 | With consent given under misconception of fact (e.g., impersonating her husband) |
| 5 | When she is of unsound mind, intoxicated, or unable to understand the nature of consent |
| 6 | With or without consent when she is under 18 years of age (statutory rape) |
| 7 | When she is unable to communicate consent |
Key Explanations and Interpretations
Consent (Explanation 2): Consent means an unequivocal voluntary agreement communicated through words, gestures, or any verbal/non-verbal communication. A woman who does not physically resist penetration shall not by reason only of that fact be regarded as consenting.
Penetration: Even the slightest penetration constitutes the offence — depth and completeness are immaterial. Ejaculation is not required — penetration is the sine qua non.
Exceptions:
- Exception 1: Medical procedures/interventions are not rape.
- Exception 2: Sexual intercourse by a man with his own wife, not under 15 years of age, is not rape (though this exception has been subject to ongoing legal challenge regarding marital rape).
Age of consent was raised to 18 years by the 2013 amendment.
Changes from Pre-2013 Law
| Aspect | Before 2013 | After 2013 |
|---|
| Acts covered | Penile-vaginal penetration only | Penis, objects, body parts, oral-genital acts |
| Consent definition | Absence of resistance implied consent | Active, communicated consent required |
| Age of consent | 16 years | 18 years |
| Exceptions | 2 exceptions | Same 2 exceptions |
| Marital age exception | Wife <15 years | Wife <15 years (same) |
The 2018 amendment further increased the minimum punishment for rape of girls below 12 years to death or 20 years rigorous imprisonment.
Part II: Evidence Collection in Rape Victims
A. General Principles
Absence of medical evidence does NOT rule out rape. Skin and mucosal injuries occur in only ~1/3 of all forced sexual violence cases. Section 375 does not require complete penetration or ejaculation. — UNFPA/MoHFW Guidelines 2014
Medical examination must prioritize treatment first, evidence second. Informed written consent must be obtained before any forensic examination.
Time window for evidence collection:
- Oral/anal assault: within 24 hours
- Vaginal assault: DNA/sperm recoverable from cervix up to 120 hours (5 days)
- General evidentiary cut-off: 5–7 days, jurisdiction dependent
B. Pre-Examination Steps
Before beginning, document:
- Date and time of assault and examination
- Post-assault hygiene activities — bathing, urination, defecation, douching, brushing teeth, eating/drinking, change of clothes (all reduce evidence yield)
- Last consensual intercourse (date, partner, acts, ejaculation — for CODIS DNA database differentiation)
- Whether rape drug (drug-facilitated assault) is suspected — collect blood and urine immediately
Instruct the victim before presenting to hospital: do NOT bathe, wash, change clothes, or clean genitals.
C. Steps in the Sexual Assault Evidence Collection Kit (Rape Kit / SAECK)
The
Sexual Assault DNA Evidence Collection Kit (SAECK) used in India contains: gloves, mask, syringes, vaginal speculum, combs, nail cutter, swabs, EDTA vacutainer, sodium fluoride vacutainer, glass slides, FTA cards, and paper bags.
| Step | Technique |
|---|
| 1. Clothing collection | Patient disrobes on a paper sheet on the floor. Each item placed separately in paper bags (not plastic — moisture destroys DNA). Collect even underwear worn after assault. |
| 2. Debris collection | Scan head to toe; collect trace evidence (fibres, paint, buttons) with tweezers or tape. Package separately. |
| 3. Biological evidence on body | Use alternate/UV light source to detect semen, saliva stains invisible to naked eye. Moisten swab with PBS/saline; swab all suspect areas. |
| 4. Fingernail evidence | Scrape subungual material with rosewood stick or moistened swab; clip nails if needed. Package and seal. |
| 5. Pubic hair combings | Comb pubic hair onto collection sheet to recover foreign hairs/fibres. Package comb + sheet. |
| 6. Head hair pulling | ~25 strands pulled (not cut) from multiple scalp sites to obtain roots for reference DNA. |
| 7. External genital swabs | Use retraction/separation technique; swab vulva and perineum; inspect for injury. |
| 8. Internal genital swabs (vaginal/cervical) | Swab posterior fornices; swab cervical os. Collect foreign objects (condom, tampon). Obtain STI cultures at same time. |
| 9. Anal/rectal examination and swabs | Inspect and swab; anoscope may be used for internal injury assessment. |
| 10. Oral swabs | Swab gum-teeth junction, tonsillar area — for semen/saliva in oro-genital contact cases. Within 24 hours only. |
| 11. DNA reference sample | Blood (EDTA vacutainer) or buccal swab from the victim for reference DNA profiling. |
| 12. Toxicology samples | Blood (grey-top NaF vacutainer) + urine for drug/alcohol screen — especially in drug-facilitated rape. |
Always use a minimum of two swabs per site — one for the crime lab, one reserved for defence if requested.
D. Swab Drying, Packaging, and Labelling
- Air-dry all swabs before packaging (do NOT use heat)
- Dry evidence → paper bags; wet evidence → label clearly, notify crime lab for re-packaging
- Each packet must be sealed, labelled, and signed with the medical officer's specimen seal
- All exhibits dispatched to the police, who forward to Forensic Science Laboratory (FSL)
E. Physical Examination — Injury Documentation
- Document all injuries using body diagrams and forensic photography (with consent)
- Use standardised terminology: abrasion, laceration, contusion, ecchymosis, redness, swelling
- Toluidine blue dye may be applied to posterior fourchette — marks mucosal micro-tears not visible to naked eye
- The Genital Injury Severity Scale (GISS) differentiates sexual assault injuries from consensual intercourse (40% tissue-disrupted injuries in assault vs. 10% consensual) — Rosen's Emergency Medicine
- Document extra-genital injuries — neck (strangulation), wrists, thighs, breasts
F. Additional Forensic Tests
| Test | Purpose |
|---|
| Semen identification | Acid phosphatase, p30 (PSA), spermatozoa microscopy |
| DNA profiling | STR (Short Tandem Repeat) — gold standard for perpetrator identification |
| Pregnancy test | Urine β-hCG if assault ≥2 weeks prior or LMP missed |
| STI screening | HIV, HBsAg, VDRL, gonorrhoea/chlamydia cultures |
| Drug screen | GHB, benzodiazepines, rohypnol, alcohol |
| UV/alternate light | Detects dried semen stains on skin/clothing |
G. Examination of the Accused
Equal emphasis must be placed on evidence from the accused:
- Penile swab (glans, sulcus, urethral meatus, foreskin)
- Pubic hair combings
- Scrotal swab
- Blood for DNA reference
- Fingernail scrapings
- Clothing
Section 375 only requires penetration "to any extent" — size/erection of penis need not be documented; potency testing (Doppler/papaverine) without consent is illegal.
H. Medico-Legal Documentation
The examining doctor must prepare:
- Medico-Legal Case (MLC) / MLR report — detailed, contemporaneous record
- Sexual Assault Victim Information Form (CFSL format) — sent with sealed exhibits
- Opinion to police/court — must note that absence of injuries does not negate rape
- Chain of custody maintained at all times — each handover documented
The doctor may be called to testify in court years later — documentation must therefore be meticulous, objective, and complete. — Rosen's Emergency Medicine, Berek & Novak's Gynecology
Important Legal Note (India-specific)
- The two-finger test (to assess vaginal laxity) has been banned by the Supreme Court (2022, State of Jharkhand v. Shailendra Kumar Rai) — it is unscientific, violates the victim's dignity, and has no probative value.
- Medical evidence is corroborative — a conviction can stand on the sole testimony of the victim without medical evidence.
